This nebula is in the western part [4] of the Perseus molecular cloud and is a young region of very active star formation, [6] being one of the best-studied objects of its type. [4] It contains a fairly typical hierarchy of star clusters that are still embedded in the molecular cloud in which they formed, [ 7 ] which are split into two main sub ...
NGC 6781, also known as the Snowglobe Nebula, [5] is a planetary nebula located in the equatorial constellation of Aquila, about 2.5° east-northeast of the 5th magnitude star 19 Aquilae. [3] It was discovered July 30, 1788 by the Anglo-German astronomer William Herschel. [6] The nebula lies at a distance of 1,500 ly from the Sun. [2]
George Willis Ritchey image of what he called the Great Nebula in Cygnus (In modern times the Veil Nebula); taken with the two-foot reflecting telescope with 3 hours exposure at the Yerkes Observatory in 1901. The nebula was discovered on 5 September 1784 by William Herschel. He described the western end of the nebula as "Extended; passes thro ...
The Red Spider Nebula (also catalogued as NGC 6537) is a planetary nebula located near the heart of the Milky Way, in the northwest of [3] the constellation Sagittarius. [4] The nebula has a prominent two-lobed shape, possibly due to a binary companion or magnetic fields and has an S-shaped symmetry of the lobes – the lobes opposite each ...
NGC 6302 (also known as the Bug Nebula, Butterfly Nebula, or Caldwell 69) is a bipolar planetary nebula in the constellation Scorpius.The structure in the nebula is among the most complex ever seen in planetary nebulae.

NGC 2440 is a planetary nebula, one of many in our galaxy. Its central star, HD 62166, [1] is possibly the hottest known white dwarf, about 400,000°F(200,000°C). The nebula is situated in the constellation Puppis. It was discovered by William Herschel on March 4, 1790. He described it as "a beautiful planetary nebula of a considerable degree ...
NGC 3132 (also known as the Eight-Burst Nebula, [2] the Southern Ring Nebula, [2] or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at 613 pc or 2,000 light-years .
